InstructPixToPixConditioningAdvanced节点是为Pix2Pix图像转换任务中的高级条件设置而设计的。它接收正面和负面的条件输入，以及新的和原始的潜在表示，以生成修改后的条件和潜在输出。该节点旨在通过允许将额外的潜在信息整合到条件设置过程中，来促进复杂的图像操作任务。

# Input types
## Required
- positive
    - 代表正面条件输入，用于引导图像转换过程朝着所需方向发展。
    - Comfy dtype: CONDITIONING
    - Python dtype: Tuple[CONDITIONING]
- negative
    - 代表负面条件输入，用于引导图像转换远离不希望的特征。
    - Comfy dtype: CONDITIONING
    - Python dtype: Tuple[CONDITIONING]
- new
    - 代表要整合到条件设置过程中的新潜在表示。
    - Comfy dtype: LATENT
    - Python dtype: Dict with key 'samples' and value as a tensor
- original
    - 代表原始潜在表示，用于与新表示进行形状一致性比较，并整合到条件设置中。
    - Comfy dtype: LATENT
    - Python dtype: Dict with key 'samples' and value as a tensor

# Output types
- cond1
    - 修改后的正面条件输出。
    - Comfy dtype: CONDITIONING
    - Python dtype: CONDITIONING
- cond2
    - 修改后的负面条件输出。
    - Comfy dtype: CONDITIONING
    - Python dtype: CONDITIONING
- negative
    - 未修改的负面条件输入，为保持一致性而传递。
    - Comfy dtype: CONDITIONING
    - Python dtype: CONDITIONING
- latent
    - 新的潜在表示，其中的样本被整合到条件输出中。
    - Comfy dtype: LATENT
    - Python dtype: Dict with key 'samples' and value as a tensor
